Salt doesnt hurt
You will tire quicker and lose weight faster. If you work a job where there is sporadic activity (ex. deliver furniture) or constant low activity (postal worker) then you’ll be fine. Construction might work too depending on the job. You will recover quickly after a short nap.
Your fat consumption will sky rocket so keep an eye on how much you have left.
The worst part of a dry fast is that you are skipping the dopamine releases coupled with food. So its a bit like kicking a nicotine addiction in that you will have cravings for specific food every now and then.
I think you can do it. But its something you have to either get used to or simply accept the suffering and embrace the suck.
I use mana soylent and take a little at a time. Its extremely easy to overeat and get poor nutrition if you give in to cravings. So I recommend something boring and nutritious to eat on the refeed. Partly because the dopamine kick will be a higher departure from baseline than normal if you eat junk and that will tempt you into food addiction.
